+ * Author: Arun Dharankar <ADharankar@ATTBI.Com>
+ *
+ * A very simple thread/schedular model:
+ *   - only one master thread, and no parent child relation maintained
+ *   - parent thread cannot be stopped or deleted
+ *   - no permissions or credentials
+ *   - no elaborate safety checks
+ *   - cooperative multi threading
+ *   - Simple round-robin scheduleing with no priorities
+ *   - no metering/statistics collection
+ *
+ * Basic idea of implementing this is to allow more than one tests to
+ * execute "simultaneously".
+ *
+ * This may be modified such thread_yield may be called in syscalls, and
+ * timer interrupts.
